Thanks for the awesome reply, amazing!
The plant's I'm growing in the tank are mosses and shady plants that aren't overly fussy about the light they receive so fingers crossed they'll be okay.
The board itself is already away from the Pi and being externally powered, with just the data fly lead coming from the Pi. So the back (completely black) side is facing upwards, I could stick on a heat-sink with some thermal paste to aid conduction? Would the Unicorn Hat allow me to pipe a direct 5v feed from it anywhere in case I decide a small slow moving fan might help?
Good idea about varying the light levels too, it could happily idle at 0.5 brightness around midday when the natural light is high.
Here's a link to the sunset run, but with no waiting times in the code so it runs at super speed! When it's fully implemented it will probably be an hour and a half from full sun to deep blue.
Thanks again for the reply.
